在我们的日常生活中，肯定会有自己非常要好的朋友，也总会有一些小秘密给我们朋友们互相分享。小时候我们就经常玩勾手指，那么长大后的我们要对方保守秘密的时候应该怎么表达呢?其实你可以这样说：

This is just between you and me.

这句话的意思就是“天知地知，你知我知”，说明两个人非常信任对方，这个秘密绝对不能给第三个人知道。这也就是我们今天要来学习的“天知地知，你知我知”了。

What happened between you and me will be safely secret and a lovely memory.

我们之间的事将会成为秘密，并且成为一段美好的回忆。

between you and me其实还可以有变体，一个是between ourselves,一个是between us，下面我们来看看几个例子吧。

Just between ourselves, I’m afraid that he is beyond all hope of recovery.

仅在你我之间说说，恐怕他完全没有康复的希望了。

I’ve warned them not to let on to him about it, because I think we can settle it between ourselves.

我不许他们去报告他，我们私下先把这件事了结了吧。

What we said today is just between us.

我们今天说得别让别人知道。

Tell no one of the secret that has passed between us.

不要把我们两人之间所说的这个秘密告诉任何人。

通常要说什么秘密之前，都要先说between you and me.

另外还有两句更酷的，一定要小声说哦：

This doesn’t leave this room.

This is for your ears only.
